BACKGROUND OF THE INVENTION (A) Field of the Invention

The present invention relates to cooling system technology, in particular to a special-shaped tube cooling and heat dissipation system that can be applied to products that require cooling or heat dissipation.

(B) Description of the Prior Art

Cooling systems are required in many industries today. Conventional cooling systems mostly use refrigerant technology to connect an evaporator, a condenser, a compressor and a piping system, so that the refrigerant changes from liquid to gas in the evaporator. It absorbs heat in the process and is used to generate cold air at low temperature. The gaseous refrigerant is transported to the condenser and then transformed into a liquid state, and the substance releases heat during the process. All systems using refrigerant cooling technology are inseparable from the above principles.

The known condenser usually adopts circular copper tube, and its cross-sectional shape is circular. Therefore, according to the isoperimetric inequality, the circumference of a circle in a geometric shape is the smallest, and the circumferential surface that can conduct heat conduction and heat exchange is also the smallest, and the wind-receiving area is only half of the circumference, and the leeward side is not affected by the wind, so the heat exchange efficiency is limited. In order to improve the heat exchange efficiency of the conventional circular copper tube, it is necessary to combine many cooling fins outside the copper tube. However, the addition of cooling fins must increase the manufacturing process and cost, and it does not change its pure air heat exchange, resulting in poor efficiency.

In addition, it is known that when the two ends of a circular copper tube are to be connected with other copper tubes to form a circuitous circulation channel, a small section of copper tube must be bent into a semi-circular connecting tube first, and then the diameter of the two ends of the above-mentioned circular copper tube must be stretched out, and then the end of the semi-circular connecting pipe must be inserted into the end of the circular copper pipe, and then the end of the circular copper pipe must be welded to the connecting pipe. Therefore, its production process is quite troublesome.

SUMMARY OF THE INVENTION

In order to solve the problems of the above-mentioned conventional technologies, the present invention proposes a special-shaped tube cooling and heat dissipation system, which comprises a cooling module, a heat dissipation module and a piping system. The cooling module comprises a cooling chip, a liquid cooling tube, a cooling fin block and a first fan for generating cold air. The heat dissipation module comprises a radiator and a second fan. The radiator comprises a plurality of heat pipes. Through the piping system, the heat of the cooling module is transported to the radiator through the liquid, and then the heat in the liquid is discharged, and the liquid is recirculated back to the cooling module. In particular, the liquid cooling pipe and the heat pipes are flat tubes extruded from aluminum alloy to increase the heat dissipation area, so there is no need to install heat dissipation fins. The liquid cooling tube and the heat pipes each define therein a plurality of flow channels, so that the liquid circulates in the multiple flow channels. The two ends of the liquid cooling tube and the heat pipes are respectively combined with a flow guide device. The flow guide devices can be used to connect to the piping system, and can also connect multiple heat pipes in series to form a circulating heat dissipation flow channel.

1. Through the structural design of the liquid cooling tube of the cooling module and the heat pipes of the radiator, aluminum extruded tubes can be used as the liquid cooling tube and heat pipes.

2. The multi-flow channel structure in the liquid cooling tube and heat pipes can make the liquid circulate in the flat flow channel, greatly increasing the stroke of the liquid flow. At the same time, the flat shape of the surrounding wall of the tube body can increase the area of heat exchange, and there is no need to install other fins to have a good heat exchange effect.

3. The flow guide devices of the present invention can be plastic components, which can combine the liquid cooling tube and the heat pipes with the flow guide devices more quickly and conveniently. The return groove structure of the flow guide devices can connect the liquid cooling tube with the multiple flow channels inside the heat pipes to extend the stroke of liquid circulation and enhance the effect of liquid circuitous flow through the radiator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1 , the special-shaped tube cooling and heat dissipation system of the present invention generates the required cold air through the cooling chip, and then removes unnecessary waste heat. Its preferred embodiment comprises one or more than one cooling module A1, a heat dissipation module B2 and a piping system C3.

Referring to FIG. 1 to FIG. 4 , the cooling module A1 comprises at least one cooling chip 10, a liquid cooling tube 20, a cooling fin block 30 and a first fan 40. The cooling chip 10 is a semiconductor that can freely cool and control temperature by direct current, and it is an existing product. one side of the cooling chip 10 is a cold side 11, and the other side is a hot side 12. According to the prior art, when the cooling chip 10 is energized, its cold side 11 can produce heat absorption, while the hot side 12 can produce heat release, and the temperature difference between the cold side 11 and hot side 12 reaches 58° C. The liquid cooling tube 20 is attached to the hot side 12 of the cooling chip 10 through a graphite heat conducting sheet or a plurality of clamps 33, and a cold liquid is input into the liquid cooling tube 20 for contact with the hot side 12 of the cooling chip 10 for heat exchange, so that the cold liquid turns into hot liquid and flows out, and then removes the heat released by the hot side 12. The cooling fin block 30 is a heat dissipation fin block made of aluminum alloy. One flat surface 32 of the cooling fin block 30 is attached to the cold side 11 of the cooling chip 10 through a graphite heat conducting sheet or a plurality of clamps 33, and the other side has a plurality of fins 31. The first fan 40 is preferably a radial fan, which is driven by a motor (not shown) to drive air through the cooling fin block 30 to generate (blow out) cool air. The first fan 40 can also use an axial fan, which can also achieve the same effect. In addition, as shown in FIG. 5 , multiple cooling chips 10 can be arranged side by side on one side of the cooling fin block 30 at the same time, and the hot side 12 of each cooling chip 10 shares one liquid cooling tube 20.

The heat dissipation module B2 mainly implements a radiator 50 and a second fan 60. The radiator 50 is used to circulate the hot liquid flowing out of the liquid cooling tube 20 in a detour, and to discharge the heat in the hot liquid. The second fan 60 is preferably an axial flow fan, which is arranged on one side of the radiator 50 to drive air through the surface of the radiator 50, so that the cold air can exchange heat with the radiator 50 to discharge the heat of the radiator 50 and the hot liquid.

The piping system C3 is a pipeline for circulating the above-mentioned cold liquid and hot liquid in the cooling module A1 and the heat dissipation module B2. It is connected between the liquid cooling tube 20 of the cooling module A1 and the radiator 50 of the heat dissipation module B2, so that the cold liquid in the radiator 50 is pumped to the liquid cooling tube 20 through a liquid pump 70 in the pipeline. The cold liquid exchanges heat with the hot side 12 of the cooling chip 10 in the liquid cooling tube 20 to become hot liquid, and the hot liquid flows back into the radiator 50 to dissipate heat and become cold liquid. Specifically, the piping system C3 comprises a first pipeline 71 that makes cold liquid flow from the radiator 50 to the liquid cooling tube 20, and a second pipeline 72 that makes hot liquid flow back from the liquid cooling tube 20 to the radiator 50. The first pipeline 71 can be provided with the liquid pump 70, and the second pipeline 72 can be provided with a liquid storage tank 80, which stores the liquid required by the system. A pressure relief valve 90 may be implemented in the second pipeline 72 to reduce excessive pressure in the piping system.

Referring to FIG. 2 , FIG. 3 , FIG. 6 and FIG. 7 , one of the main features of the present invention is that the above-mentioned liquid cooling tube 20 is a straight tube extruded from an aluminum alloy, and it is a flat tube whose width in the cross-sectional direction is greater than its height. The liquid cooling tube 20 is internally formed with three flow channels 21 a, 21 b, 21 c leading directly to its two ends, and there is an integrally formed partition plate 22 between each of the flow channels 21 a, 21 b, 21 c. The two ends of the liquid cooling tube 20 are respectively combined with a first flow guide device 23, and the first flow guide device 23 at one or both ends of the liquid cooling tube 20 corresponds to the inner surface of the liquid cooling tube 20 and is provided with a first return groove 231 communicating between two flow channels, so that the flow channels 21 a, 21 b, 21 c of the liquid cooling tube 20 form a circuitous circulation structure (as shown in FIG. 6 ) through the first return groove 231, prolonging the time of liquid circulation and heat exchange. The first flow guide devices 23 can be respectively provided with a first liquid inlet pipe 24 and a first liquid outlet pipe 25, and the first liquid inlet pipe 24 and the first liquid outlet pipe 25 are respectively used to be connected to the above-mentioned piping system C3.

Referring to FIG. 8 , FIG. 9 and FIG. 10 , another feature of the present invention is that the above-mentioned radiator 50 comprises a plurality of heat pipes 51, and a second flow guide device 52 combined at each of both ends of each heat pipe 51. The plurality of heat pipes 51 are arranged in parallel at a distance from each other. Each of the heat pipes 51 is a straight pipe extruded from aluminum alloy, and each of the straight pipes is a flat pipe whose width in the cross-sectional direction is greater than its height. Each of the heat pipes 51 is internally formed with three flow channels 511 a, 511 b, 511 c leading directly to its two ends, and there is an integrally formed partition plate 512 between each of the flow channels 511 a, 511 b, 511 c. Referring to FIG. 11 and FIG. 12 , each second flow guide device 52 is provided with at least one return groove 521 corresponding to two flow channels of the respective heat pipe 51. One of the second flow guide devices 52 is provided with a second liquid inlet pipe 53 and a second liquid outlet pipe 54 (as shown in FIG. 8 ). The second liquid inlet pipe 53 and the second liquid outlet pipe 54 are respectively connected to the selected return groove 521, and the other end is connected to the first pipeline 71 and second pipeline 72 of the piping system C3. In this way, the two ends of the heat pipe 51 are hermetically bonded to the return groove 521, the return groove 521 is connected between two flow channels of the heat pipe 51, so that the hot liquid flow circuitously in the flow channels 511 a, 511 b, 511 c in one heat pipe 51, prolonging the time of liquid circulation and heat exchange.

Referring again to FIG. 8 and FIG. 9 , the upper and lower sides of the second flow guide device 52 are provided with connection pipes 55, 56 connected to the return groove 521 or flow channels, so that the second flow guide devices 52 at both ends of the heat pipes 51 arranged in parallel to the radiator 50 are connected up and down through the connection pipes 55 and 56. In this way, the hot liquid circulates among the three flow channels 511 a, 511 b, 511 c in one heat pipe 51 (as shown in FIG. 11 ), and then flows through the connection pipe 55 and 56 to the next heat pipe 51 and then circulate in a circuitous manner (as shown in FIG. 12 ), and then flows to the next heat pipe 51. By connecting many heat pipes 51 in series in this way, the circulation stroke of the hot liquid can be extended, and its heat exchange effect can be improved, and good heat dissipation efficiency can also be achieved without implementing conventional heat dissipation fins on the outer wall of the pipes.

Referring to FIG. 1 again, the above-mentioned pressure relief valve 90 is connected to the second pipeline 72 or first pipeline 71 of the piping system C3. The inside of the pressure relief valve 90 is implemented with an expandable and contractible ball 91, so that the cold liquid or hot liquid under high pressure flows to the ball 91 of the pressure relief valve 90, and when the pressure drops, the liquid in the ball 91 is returned to the circulation system.

In addition, a water receiving tray 100 may be provided under the cooling module A1, and the water receiving tray 100 is used to receive water droplets condensed by the cooling module A1. The water receiving tray 100 can also be connected to the piping system C3 to apply the recovered water to the cooling and heat dissipation system.
